I'm not sure what you're saying... Any of the Status Toolbar buttons are equivalents of their menu counterparts, so clicking the "New Record" button there would run the same script as the "New Record" menu item when part of a custom menu.

You must forgive me, but my solutions in the past have the status bar hidden, but on the latest soltuion, I am showing it. So I need to be able to trap the action as a script. So all I need to do now is create a custom menu set and viola! Yay!
